IMPRQVEMENT IN' LAMP-BURNERS. l

` y TheiSchedulerefen-ed to in these Letters Patent and making part of the `taime. v

of the county f; Suffolk `andState of Massachusetts, have made a new andfuseful invention havingreference to Burners for Lainps`,=cspecially those i used for obtainingflight from the combustion of kerosene or i other fluids rich incarhon; and I Vdohereby declare vthe same to be fully described in lthefollowing specitication4 andrepresentedin .the accompanying drawing,

of which` u .Y

FiguresA 1 and 2 are side elevations, and

y `Figures and 4 transverse sections of my improved y y zfIhe'natureof my inventioneonsists in a peculiar` constructionaud-aarrangemeut of parts, whereby the wick-holder, or` such and iitsl wick-elevator, `and the lease thereto, arecombined withll'a foraminous dishcd. slider,.so as to be "movable therewitlnand the latter is supported by, so` as` to slidevertically inv standards or posts' connect-ingthechinuieyholder audits de- `iector with the cap-screw for `fizing the burner to the and as having thel detiector and a foraminous cup movablc vertically onthe ivickltube and relatively: to` the chimney-holder. if f Y L In theUnited States` Patent No.'73,600, `there are i similar arrangements ofthe parts, except that the de- Hector does not slide` with the foraminous cup, but rests on the chimney-snpporter.`.

In `the United States Patent No. 75,483,13hedelector, thel foraminous chimney-holder, and cup, are

f stationary relatively to the screw-cup, and supported byfstandards erected thereon, thewick-tube and its wick-elevatorbeing movable `vertically relatively to Such parts. i

I make no -clair'n burner, while having the wick-tube movable vertically i for the `purpose of enablingit )to be depressed to ad# i mit of its wick being readilytriinmed, has such tube and "its"v wick-elevator so combined with the foraminous y guard or cup as to move with itand bey supported by y to` either of Athe three constructions or arrangement-s of devicesas 1last referred to, as my it, whereby advantages in the appearance, construction, and operation of the burner are attained. a In the drawingv A denotes the wick-tube;

B, the 'screw-cap; and Y a C C, two standards erected on such cap.

These standards support the chimney-holder D, provided `with a cone or deficetor, E, and with the usual means of supporting and fastening a glass-chimney to such holder. l

The box F, containing the wick-elevator, toothedwheel or wheels (t, and the supporting-shaft?) thereof, is fastened directly to and encompasses the wick-tube,

and israiso fastened to a foraminous guard or cup, G,-

forrned as shown in the drawing, and arranged to slide vertically on the posts or standards G C.

, A springllatch, H, fixed to the wick-tube, and` formed/and arranged therewith and with the screw-cap,

`as represented, serves, when the guard or cup G andthe wick-tube are in their highest-positions, t'o hold them there7 a slight downward pressure exerted on the cup being sucient to. overcome the `hold of the latch and cause the Vdescent of such cup, the wick-tube, and the.

wick-elevator. y I v y I am aware of the United StatesPatent No.36,367,` and make no claim to any device, combination, or arrangement of devices represented or described therein. My construction of theburneratords much easier access to the wick for the purpose of trimming it', and

is better in various other'.respects.v

` ThatI claim is as follows:

As an improved manufacture, the burner as de-` scribed, as having the wick-holder, or such and the wick'- elevator, and the case thereto, combined with .the foraminous dished slider, and such` slider supported on andby posts C' O, so Aas to play vertically thereon, connecting the lchimney-holder and its deector with the cap-screw for xing the burner to allamp-reservoir, the whole being' as represented.

Also, the arrangement of the spring-latch with the Wick-tube, the Screw-cap, and the foraminous cup, ap,- plied together and' to operate aseexplained.
